 // if we use 20 we are limited to 1% duty cycle or hw might overheat.  For continuous operation set a limit of 17
 // In theory up to 27 dBm is possible, but the modules installed in most radios can cope with a max of 20.  So BIG WARNING
 // if you set power to something higher than 17 or 20 you might fry your board.
